4 What We Do Our Recent Efforts Asset Management Planning Utility Mapping

5 What is Asset Management Planning? A process that helps ensure: 1. Know your system assets 2. Get the most production from them 3. Have the financial capacity to replace and repair them when needed.

6 Asset Management Planning INVENTORY CONDITION ASSESSMENT Know your system assets RISK OF FAILURE ASSESSMENT PRIORITIZATION OF ASSETS

7 Asset Management Planning Get the most value from them and be ready to repair or replace when needed.

8 Create a Better System through Asset Management Run to Failure and Unintended Failure o Inadequate budget o Lack of will o Lack of maintenance Preventative Maintenance And Know when to quit (Replacement) Adequate budget Strategic investments Knowing and acting on the age, condition, or impacts to the overall system of asset failure.

11 LRCOG Asset Management Program Purpose: to provide local governments with useful information upon which to base rehab and replacement decisions. Utilize EPA s CUPSS software for inventory purposes. Develop the client reports by adding other useful data- rates and rate structures, task manager for maintenance, etc. Now used by staff day-to-day and by elected officials in decisions on rates and investments.

14 Typical Sewer System - Asset Age and Value Current system comes online in 1940s. Most clay lines date to this period. Line extensions. Last significant modification was addition of a sewer lift station and extension of sewer to the industrial park. Treatment Plant modified in

The useful life of these lines has long expired and maintenance needs are growing. Contract with an electrician to review the potential costs. Plan for upgrade or replacement.

18 Utility Mapping

19 We have connected Utility Mapping to Asset Management Planning Each asset is assigned an ID number all data tied to that number. Allows us to archive and display individual asset data. Allows to create system level, detailed maps. Maps renewed as the asset profile is updated.

20 Today Utility Mapping Purpose: to archive information and produce a useable system map showing the best available data. Developed a GIS-based platform that allowed for the creation of a published map usable without the purchase of ESRI software. Utilized EDA and Rural Center grants to help apply GIS mapping program to pilot towns. Replicated this effort in three other COGs as part of a Rural Center grant. Used by staff day-to-day and to show local officials the real size and complexity of their water and sewer utility systems, base data for planning, rate studies, customer base assessments, etc.

25 Our Findings and Conclusions Asset Mapping work is a logical extension of the LRCOG s ongoing educational effort for water/wastewater utilities of our local governments what our systems need right now. Through creative and strategic use of resources, we are able to perform this work cost-effectively for small systems. With modifications, the CUPSS Program offers an affordable tool that is easily understood, can be used by local officials and staff, and is replicable.

26 Findings and Conclusions Though the sample is small at present, indications are that things are worse than previously thought and under more threat of significant failure than sewer systems. Groundwater systems: Aged Well Infrastructure These findings on small water systems should inform State policy. While not possible for some (question of cost effectiveness) we still maintain that regionalization of small water systems may help address the overarching problem of an inadequate customer base to generate needed revenue.
